The first image shows him lacing up new shoes, which are notably yellow on a mountain of red shoes that his running has seemingly blown through. The second provides a brief glimpse of his prototype costume, which includes a hood and backpack. It's worth noting in the first image that Barry has also got elbow and knee pads on, hinting that he fully hasn't learned how to perfect his speedster powers.

The book is also confirmed to be canon and compares to how Batman: Year One took place within the Dark Knight's ongoing run.

Williamson has been writing The Flash since 2016 and recently wrote Justice League Odyssey (and its direct predecessor, Justice League: No Justice), while Porter has provided art and interiors for The Flash since Williamson took over writing duties. Williamson often tweets out the covers and art that Porter provides for him in the lead up to the issue's release.

The last "Year One" storyline for The Flash took place in 1992 during writer Mark Waid and artist Greg LaRocque's The Flash #62-65 and served as a new origin for Wally West. The story arc was also subtitled, "The Flash: Born to Run."
